Only have access to 50% of my battery.

For the last week my nexus 7 has been completely dying around 50% battery. If its in sleep mode when it hits that % then it won't turn on, if I'm using it when I hit that % I get a weird flicker then it shuts off. This just seems extremely strange that all of a sudden only half my battery works. A long with only having half my battery to work with, it seems like the tablet has been charging a lot slower then normal. I use to be able to work it down all the time and usually didn't charge it until 5%-10%
Anyone else ever have this issue? I contacted Asus and there only solution right now was a factory reset. I cant see how that could fix the issue at all.

are you rooted? what type of kernel are you using?

I have read that sometimes a factory reset refreshes the battery settings. Is your device rooted or rommed out?

That happened to one of my friends S2's. Factory reset it. It worked for my friend. My N7 also charged really slow. I just changed the ROM. It is the same thing as a factory reset because you do one when you change your ROM.

As said before, try a factory reset !
If no luck there
Try download a battery calibration app to see if its mis-calibrated etc

Is there a fix for slow charging issue?

Since i updated my device to 4.2.1 charging my nexus 7 really get slow..... It takes 6 hours to 7 hours to fully charge. Im using the cable and charger that it came from the unit.
Is there a fix for this one? Thanks.

AW: Is there a fix for slow charging issue?
Check whether the device charges in USB mode. It can happen for some reason I don't know. In this mode it charges much slower. I once had it happen when on AC.

It's on AC. It takes 6 hrs to fully charge from empty. =(

What do you mean by rebooting it? I have the same charging problem. It needs about five to six hours for me to charge fully. How did you solve it? Is it really the problem of android 4.2.2?

Just try rebooting it or restart the device while charging. Im using battery widget reborn app, to see how many hrs left to make my nexus 7 to be fully charged.
Here's what i do,
Plug the charger then check after 2 mins on the app battery widget reborn how many hrs left to be fully charged, if it's says more than 4 hrs or greater than that. Hit the power button and restart your device. Once the device booted up, check the remaining time left on charging if it's improved to 3 hrs or less to fully charged your device.
Try it. It's working fine for my nexus 7.

I tried the app you mentioned. But the remaining time it indicates isn't equivalent to the real time used. Maybe this app doesn't work for my device, it still needs four to five hours for my nexus being fully charged. Anyway, thanks for your reply.

Or you may try to go to bootloader, then turn it off.. Unplug the charger, then put it back in then turn on your device.. It works for me.

Strange problem with nexus 4

My friend recently bought an imported nexus 4 from eBay(on my advice). He's having a strange a problem. The device works normally till the battery drains below 50%. But then it suddenly turns off and doesn't turn back on again. When he connects the charger, it's stats charging from 0% again. The charging process is also normal.
Anyone had this type of problem?

Whats the rom and kernel?
Sent from my Nexus 4 using XDA Premium 4 mobile app

Try charging it to 100%, disconnect charger, reboot and check if it already lost some charge during reboot. If yes charge full again.
I had something similar (not a total drop, but a fast drop when below 50%) a few days ago and this helped. I don't know why, though.

I think you should try both suggestions.
Also inform us what is the ROM and Kernel he is using.
Keep us updated.

No. Why?

Wont charge while device is powered off. Charges fine when its on. I guess thats all for it, might be a bad cable.
